Based on different discussions in Twitter, Together -community, talk-maemo.org etc. it seems to be comfirmed that SailfishOS cannot use FM-chip inside Qualcom Snapdragon 400 -soc. (antenna, wiring etc. are the issue)

It has been suggested that special OtherHalf would be built which included FM-tuner.

Great idea indeed! But those components are rather large, arent they?

Totally agree, a fantastic idea, let's do it..

If a radio other half would be made then I would vote for making a really awesome receiver that would stand out from the crowd and not just a cheap receiver that doesn't almost pick up any channels. Maybe add a small LCD to the other half too for the radio and a retractable antenna :)

You may want throw in also some additional bluetooth circuitery, so to avoid having a device with two headphone jacks.

Would be sweet to have both an FM and a DAB+ reciever in the same TOH. At least in DK many of the FM stations are being phased out in favour of DAB.

INFO: I decided to move this answer by Kaacz into answer section. This answer is wiki, so any special karma won't be added to anybody.

@Kaacz answered in the different thread (https://together.jolla.com/question/2111/hardware-feature-request-would-it-be-possible-to-enable-fm-radio-hw-in-the-2nd-jolla-hardware/) like this:

OK. Final info. FM chip exist but without connection anywhere. :( For solution in ToH I found few i2c controled FM receivers. Cheap & all-in-one.

RDA5807M - output right to headphones."

What's missing is the TOH project itself :) We have lately seen promising examples of the projects where early versions of TOHs whith display or keyboard has been developed. What we miss is the FM-TOH project.

I've found some other all-in-one FMreceiver i2c compatible, sometimes with more functions compared with the proposed TEA and RDA. I'm making a preliminary study about various solutions, about antenna RFIN and what to do with L/Rout 'cause are always proposed to drive a ear/headphone, not good for us

@gordon_pcb_designer, I saw message sent by you in talk.maemo.org where you asked about internals of the phone (antennas etc.) in order to know what might be best place for FM antenna in FM-TOH!

It was so nice to see that message ;) I hope that tinkering to get FM-TOH will start as soon as possible ;)

@LaruX: Nice to read your comment.. at the moment i'm looking for some different solutions and apporaches but i've got 2 big problems:

  1. i'm totally below zero about SW (I2C interface to manage HW)

  2. i'm not sure how and if i can deliver L/R signals to system earphone connector :D

What are last informations about this subject?! It is also very surprising that there are no TuneIn apps ! Is somebody working on it or the priority is for keyboard and other TOH !?

Many tablet&phone customers would like a radio-receiver and some a transmitter, I guess. Is TOH doing anything? I'll also miss a keyboard and cover for the tablet when it comes in May – looking forward! :-)
